termios

问题 i am trying to clear text by pressing the backspace key, i am using termios in non canonical mode. i have created a conditional statement that when the users press backspace it should remove the previous character by going one character back. But when i press Backspace instead of removing the character it prints ^? on that line. I don't want to use canonical mode. My Code: #include <stdio.h> #include <stdlib.h> #include <termios.h> #include <unistd.h> #include <sys/types.h> #include <string.h

问题 Now that we've reached Swift 2.0, I've decided to convert my, as yet unfinished, OS X app to Swift. Making progress but I've run into some issues with using termios and could use some clarification and advice. The termios struct is treated as a struct in Swift, no surprise there, but what is surprising is that the array of control characters in the struct is now a tuple. I was expecting it to just be an array. As you might imagine it took me a while to figure this out. Working in a Playground

问题 I'm using .NET Core on an embedded Linux platform with good success so far. I just ran into a problem with trying to open a tty device in raw (noncanonical mode) though. If I was using regular C or C++ I would call cfmakeraw() after opening the device, but how do I do that from a .NET Core app? The device I need to work with is a CDC ACM function driver for the USB client connector, i.e. it's a virtual COM port. It appears in my system as /dev/ttyGS0 . I can open the device and then read from

问题 Apparently this is almost a duplicate of "Bad pipe filedescriptor when reading from stdin in python - Stack Overflow"; however, I believe this case is slightly more complicated ( and it is not Windows specific, as the conclusion of that thread was ). I'm currently trying to experiment with a simple script in Python: I'd like to supply input to the script - either through command line arguments; or by 'pipe'-ing a string to this script - and have the script show this input string using a

问题 In my particular situation I am using MinGW/MSys . It doesn't contain termios.h . Turns out it isn't a library that can be downloaded and installed (google didn't found any). Termcap also doesn't include termios.h . Where from to get this file? 回答1: MinGW doesnt fully support POSIX and therefore termios.h is missing. On the other side, Cygwin is capable of POSIX and termios.h. 来源： https://stackoverflow.com/questions/20772965/where-to-obtain-termios-h

问题 Extensive searching on the use of raw mode with termios and xterm leads to numerous references to a "timing trick" required to distinguish between an escape-sequence and a lone appearance of the escape character. So how do you do it? I don't want to use curses because I don't want to clear the screen. This is for a calculator-style program, so it's important to retain the "ticker-tape" interface. 回答1: finally found a nice detailed description in an old usenet thread. I quote the relevant

问题 I want to use some of the functionality of <termios.h and <asm/termios.h> , but they contain functions with the same name, and only including them both I got error: redefinition of 'struct termio' . I managed to use some of <asm/termios.h structures ( struct termios2 ) by isolating the #include directive exactly where I need (in a function). void MyClass::MyMethod() { #include <asm/termios.h> struct termios2 tio; // do stuff with tio variable. } This works fine for only one function, but if I

问题 I'm developing on an am335x system with ubuntu and the last kernel released from TI (vendor). I'm using a virtual tty device (ttyUSB0) for comunicate with a remote device. After about one hour of continuous comunication (cyclic open-transmit-receive-close) I get a strange behaviour of read(). If the UART is opened in blocking mode the read hangs forever (no matter what value I set on VMIN&VTIME). If I open it in non-blocking mode it return -1 for ever (after 1 hour). Now I'm using select() to
